The myelinated fibre content of human inferior alveolar nerves from dentate and edentulous subjects

Morphological variability of the human inferior alveolar nerve

“…When the teeth, and consequently the bone, are lost the vessels atrophy. The observed reduction in size of the IAN is consistent with the finding of Heasman (1984), who has reported fewer myelinated fibers in the nerve in edentulous subjects compared with dentate subjects. The proportion of fibers subserving the stimuli for pain, temperature, touch, pressure, and proprioception was the same in dentate and edentulous subjects.…”

The mandibular canal of the edentulous jaw

“…In the present study, microscopy frequently showed small nerve bundles, rather than a distinct neurovascular bundle, anterior to the mental foramen. Neuronal loss after tooth extraction was described by Heasman (1984). We confirmed the findings of Wadu et al (1997) that, in the edentulous mandible, veins were indistinct.…”

The Superior Alveolar Nerves: Their Topographical Relationship and Distribution to the Maxillary Sinus in Human Adults

“…In contrast, 4.2% of myelinated fibers of the anterior superior alveolar nerve, which merged directly into the superior dental plexus, seemed to be A-y fibers for proprioception ( Table 1). The fiber composition of the anterior superior alveolar nerve was similar to that of the inferior alveolar nerve (Heasman, 1984) and dental pulp (Reader and Foreman, 1981;Jonsen et al, 1983;Nair et al, 1992). These results suggest that fibers in the nerve plexus of the maxillary sinus are different from those in the superior dental plexus.…”

“…The plexus appeared not to contain A-y fibers for proprioception according to Noback and Demarest (1981) and to Heasman (1984). It is unlikely that the convergence of the plexus to a small diameter was caused by aging or tooth loss, since the diameter range of myelinated fibers innervating teeth has been reported not to change with either aging (Johnsen et al, 1983) or tooth loss (Heasman, 1984). In contrast, 4.2% of myelinated fibers of the anterior superior alveolar nerve, which merged directly into the superior dental plexus, seemed to be A-y fibers for proprioception ( Table 1).…”

“…Moreover, the fiber composition of the nerve plexus of the maxillary sinus was different from that of the superior alveolar nerves innervating the upper teeth ( Table 1).
